Primitive low-level header file changes
by Kyösti Mälkki 04 Mar '19

04 Mar '19

Hi folks! In order to (better) support other than X86 to have PCI support, headers with primitive low-level accessors have been re-organised as follows: For any MMIO access, <device/mmio.h> read8/16/32/64() write8/16/32/64() For any PCI configurations, <device/pci_ops.h> pci_read_config8/16/32() pci_write_config8/16/32() pci_or_config8/16/32() pci_update_config8/16/32() For X86 (or other) IO space, <arch/io.h> inb(),inw(),inl(),insb(),insw(),insl() outb(),outw(),outl(),outsb(),outsw(),outsl() For PNP configuration (pre-ram), <device/pnp_ops.h> pnp_read_config(), pnp_write_config() pnp_set_XX(), pnp_read_XX() My current advice is you don't need to include <device/pci_type.h> or <device/pnp_type.h> explicitly. Regards, Kyösti

t420s USB 3.0 port
by Jason Andryuk 04 Mar '19

04 Mar '19

Hi, I have a Lenovo Thinkpad t420s on which I've installed coreboot. However, the USB 3.0 port is not active and the controller is not listed under lspci. Under the original Lenovo bios, the xhci device was at pci address 0d:00.0 behind bridge 00:1c.4. It looks like the t420s devicetree.cb is set up for the xhci controller to be behind 00:1c.6. I changed that to 00:1c.4 and that got the xhci pci device to show up as 03:00.0. Strangely, booting into linux, it shows 001c.3 as the bridge to 03:00.0. Additionally, plugged in USB devices were not detected. Here's where it gets weird. I had a mouse plugged in, and I was looking in sysfs. cat /sys/devices/pci0000\:00/0000\:00\:1c.3/0000\:03\:00.0/enable 0 So the xhci pci device is disabled. I ran `lspci -vvnn` a few times in quick sucession - I was looking to see if it showed disabled - and the mouse lit up! Plugging in a USB Flash drive, it was again not detected. The lspci trigger worked. Later, promptly switching USB devices resulted in the new USB device still being detected. Is "PCH: PCIe map 1c.4 -> 1c.3" the remapping from the device tree 1c.4 to the 1c.3 that I see? Below I've included the cbmem -c output and a snippet from an old lenovo BIOS dmesg w/ the pci address. Does anyone have an idea of what is going on, or what I should investigate next? A total guess, but could poking the PCI device with lspci turn it on so that it may detect an attached device and then stay active? Maybe something with power management? Again, I'm just guessing. Any suggestions are appreciated. Thanks, Jason Old linux dmesg from Lenovo BIOS: Dec 6 01:55:52 ubuntu kernel: [ 10.077337] pci 0000:0d:00.0: >[1033:0194] type 00 class 0x0c0330 Dec 6 01:55:52 ubuntu kernel: [ 10.077382] pci 0000:0d:00.0: >reg 10: [mem 0xf0c00000-0xf0c01fff 64bit] Dec 6 01:55:52 ubuntu kernel: [ 10.077610] pci 0000:0d:00.0: >PME# supported from D0 D3hot D3cold Dec 6 01:55:52 ubuntu kernel: [ 10.077701] pci 0000:00:1c.4: >PCI bridge to [bus 0d-0d] Dec 6 01:55:52 ubuntu kernel: [ 10.077714] pci 0000:00:1c.4: > bridge window [mem 0xf0c00000-0xf0cfffff] cbmem -c dump: *** Pre-CBMEM romstage console overflowed, log truncated! *** 666 MHz Selected CAS latency : 9T PLL busy... done in 50 us MCU frequency is set at : 666 MHz Done dimm mapping Update PCI-E configuration space: PCI(0, 0, 0)[a0] = 0 PCI(0, 0, 0)[a4] = 4 PCI(0, 0, 0)[bc] = 82a00000 PCI(0, 0, 0)[a8] = 7d600000 PCI(0, 0, 0)[ac] = 4 PCI(0, 0, 0)[b8] = 80000000 PCI(0, 0, 0)[b0] = 80a00000 PCI(0, 0, 0)[b4] = 80800000 Done memory map Done io registers t123: 1912, 9120, 500 ME: FW Partition Table : OK ME: Bringup Loader Failure : NO ME: Firmware Init Complete : NO ME: Manufacturing Mode : YES ME: Boot Options Present : NO ME: Update In Progress : NO ME: Current Working State : Initializing ME: Current Operation State : Bring up ME: Current Operation Mode : Debug or Disabled by AltDisableBit ME: Error Code : No Error ME: Progress Phase : BUP Phase ME: Power Management Event : Clean Moff->Mx wake ME: Progress Phase State : Check to see if straps say ME DISABLED ME: Wrong mode : 2 ME: FWS2: 0x100a0000 ME: Bist in progress: 0x0 ME: ICC Status : 0x0 ME: Invoke MEBx : 0x0 ME: CPU replaced : 0x0 ME: MBP ready : 0x0 ME: MFS failure : 0x0 ME: Warm reset req : 0x0 ME: CPU repl valid : 0x0 ME: (Reserved) : 0x0 ME: FW update req : 0x0 ME: (Reserved) : 0x0 ME: Current state : 0xa ME: Current PM event: 0x0 ME: Progress code : 0x1 Waited long enough, or CPU was not replaced, continue...

Microcode in ROM is not loaded with X60s
by Masanori Ogino 04 Mar '19

04 Mar '19

Dear Coreboot developers, I installed Coreboot with ThinkPad X60s and Debian 9 and they run successfully, but I observe a weird behavior. Even though I had enabled blob for microcode update, the system seems to run without it. I saw the following message in dmesg: (I think this is not fatal since this is related to temperature monitoring, though.) > coretemp: Errata AE18 not fixed, update BIOS or microcode of the CPU! For comparison, I had installed `intel-microcode` package to the system and then the message disappeared. Is this intended behavior, misconfiguration, or a real bug? For reference, I uploaded the content of /proc/cpuinfo before and after the installation of `intel-microcode` package: https://gist.github.com/omasanori/4a1316bd78d95069f287431f5bd3a176 Also, I uploaded a report to board-status: https://review.coreboot.org/cgit/board-status.git/commit/?id=af91ae4946fec9… (I had also tried to install FreeBSD 12.0 and OpenBSD 6.4 but both of their installers failed to boot just after the kernel is loaded and located. I am not sure if this is related to this or not.) Best regards, Masanori -- Masanori Ogino

Shubhendra - GSoC proposal Inquiry about "Port payloads to RISC-V"
by Shubhendra Singhal 03 Mar '19

03 Mar '19

Dear Sir/Ma'am, I am Shubhendra Pal Singhal, currently third year in Computer Science at NIT Trichy, India. I wish to apply for Google Summer of Code. I looked into the profile of coreboot 4.9 and found out the project idea "*Port payloads to ARM, AArch64, MIPS or RISC-V*" to be very interesting. I have worked in the similar field on *RISCV architecture at IIT Madras where I helped in porting real time OS eChronos*, on RISCV architecture. I will be undergoing a *project in Embedded systems offered by USC Los Angeles in solving the SAT Solvers using OS and Digital Logic*. Furthermore, I am currently working on a *long term project with under Prof. N.Ramasubramanium on the AI chip* where we are trying to solve the processing speeds by efficiently reducing the number of writes in the cache for faster access. I am also *undergoing Microcontrollers and Microprocessors* as my core subject in my current semester and have already* undergone OS, Real time Systems* in my B.Tech IV semester. I have included my further details in my Linkedin : * <https://www.linkedin.com/in/shubhendra-singhal-7378a9131/>https://www.linkedin.com/in/ <https://www.linkedin.com/in/>shubhendra-singhal-7378a9131/* I want to contribute to the open source community in the field of Operating Systems and this can prove to be an excellent platform for gaining experience in field of systems. This opportunity can pave my career, towards applied research in the field of Systems. *While browsing through the link, I saw the mailing list assigned for the project. It would be very useful if you could guide me as to what is expected in the project proposal and how can I serve the open source community in the best possible way. *Any guidance would be very useful and I hope to receive a reply soon. Thanking you for your time and consideration.

Get a working bootsplash.bmp BMP splashscreen for SeaBIOS with this ImageMagick command
by Mike Banon 02 Mar '19

02 Mar '19

Why BMP? It's a lossless image format which could be LZMA compressed quite well depending on the image's variety of colours. And finally I found out how to get a working splash screen - instructions tested on AMD Lenovo G505S laptop with 1366x768 screen resolution : 1) Install the ImageMagick package, it has a "convert" tool. 2) Find a cool image, preferably in a lossless format like PNG (certainly not a lossy JPEG!), resize it to your screen resolution - e.g. to 1366x768 in this particular case - and save it, preferably as PNG. 3) Now you could convert this image into BMP format recognizable by SeaBIOS: convert ./wallpaper.png -alpha set -verbose -depth 32 ./bootsplash.bmp 4) Then add it to your coreboot.rom image, with LZMA compression of course - because without a compression those BMPs are too large: ./coreboot/build/cbfstool ./coreboot/build/coreboot.rom add -f ~/Downloads/bootsplash.bmp -n bootsplash.bmp.lzma -t raw -c lzma 5) And finally flash the updated image, e.g. at G505S it could be flashed internally: sudo ./flashrom/flashrom -p internal:laptop=force_I_want_a_brick,amd_imc_force=yes -w ./coreboot/build/coreboot.rom Hope it's helpful! Best regards, Mike Banon

Hi, I'm working on Intel Braswell implementation and uploaded several patches. It seems that the maintainer of the Intel Braswell is not active for review/merge/reply of the uploads. Is the maintainer in MAINTAINERS document correct and still active? Met vriendelijke groet / Best regards, Frans Hendriks Eltan B.V.
